AUTOMOBILE CONSTRUCTION.

To all whom it may concern:

Be it known that I, Lnwrs L Soorr, a citizen of the United States, residing III the city of St. Louis and State of Missouri, have invented new and useful Improvements in Automobile Construction, of which the following is a specification.

This invention relates to automobile construetion, and particularly to the mounting avoid any substantial increasin of an accessory, such as an electric generator adapted to be driven from the engine or motor'of the automobile.

It has been proposed to support such a generator on thehousin'g of the rear axle and drive the same from'the rear side of the difierential gear. This arrangement has the objection of increasing the unsprung weights on the axle. Y The general object of the present invention is to provide simple means for supporting and driving such an accessory which Will sprung axle load, in other wor s, the parts are so organized that the generator is driven fromthe engine though its weight is 'practically supported on-the automobile springs.

The invention is described in the followingspecification'as applied to" a steam driven automobile.

Further objects of the invention will appear hereinafter. I} g I The invention'consists in the general combination of parts tobe particularly de'-.

scribed hereinafter, all ofawhich' contribute to produce a simple and efficient automobile construction. -A preferred embodiment of my invention will be described in the following specification, while the broad scope of my invention will be pointed out 1n the appended claims.

In the drawing,

Figure l is a plan and partial section illustrating the general arrangement and organization of the parts; and

Fig. 2 is a diagrammatic viewin elevation illustrating a detail of the means which I may employ for driving the generator.-

Referring particularly to the parts, 1 represents an automobile frame of an desired construction, and comprising side bars, 2 which are supported by springs 3 on the rear axle housing; this housing is composed of two tubular housing parts, or housings 4. The engine comprises an engine frame 5 which is supported at its rear end on the Specification of Letters Patent.

axlehousing and at its forward end on the frame 1; for this purpose, the: rear end of the frame is ing bearings 6 for the axle sections 7 which constitute the rear axle. The adjacent ends of the axle sections'7, carry adifferential Wheel 8 which is disposed within the engine frame 5. The cylinders of the engine'are numeral '9, and from the head guides 11 where they are attached to connecting rods 12.

The crank shaft 13 of the engine is disposed parallel with and adjacent to the rear axle, and suitable means is provided for rotatably supporting the crank shaft between the cranks-14 that connect to the rods 12.

For this'purpose I'provide two inboard bearlngs 15 located respectively, on opposite sldes of a driving gear wheel 16 which provided with openings carrymeshes with the differential gear wheel 8.

The inner ends of the axle housings 4 are bolted to the sides of the engine frame 5, so that the weight of the rear portion of the en-- gineis carried on'the axle housing; the forward end of the engine has a point of suspension on theframe 1 for Wlll'Ch purpose the cross 'bar 1-7 of the frame may be provided with a bracket 18 from which the forward end of the engine is suspended on a laminated'strap 19.

In applying my invention to such a con st'ructiontas I have outlined above, I provide an electric generator and mount it at any suitable point on the engine forward of the rear axle; in this way, part of the weight of the generator will be supported on .the frame at the point of suspension 18. I prefer to provide an electric generator 20 which is attached as near as convenient to the point of suspension, that is to say, it is mounted on the side of the engine and toward the end of the engine which is adjacent to the point 1 of suspension. This will place the generator as far aspossible from the rear axle,and hence as much as possible of its weight will be supported on the frame; in this way,

most of the weight of the generator will be spring-supports Any suitable means may be provided for driving the generator, but I prefer to employ. inboard bearings, such, as described above, because they enable me to employ a very simple and novel driving means for driving the generator. In order to effect the drivin of the generator aim Jl aroin one of vide a pin-and-slot connection theicranks to a stub shaft 2 onnted in the side of the engine frame, 1 operating through bevel gears 22 and 23 to drive a shaft 24: which is coupled to a. generator shaft 25. The bevel gear 23 is preferably a pinion, so that the generator shaft will be driven at a considerably higher speed than the engine shaft.

The pin-andslot connection may be such as that illustrated, comprising a pin 26 carried on the adjacent crank let and received inma slot 27 formed in the end of an arm 28 which isrigid on the stub shaft 2L. The pin 26 need not fit at all closely:

,in the slot 27, and-hence it does not interfore in any way with assembling the parts,

. forexample, the stub shaft 21 and the gears 22 and 23 may be conveniently carried in a' gear .box 29 which may be bolted in an opening on the side of the engine,

' It is understood that the embodiment of the invention herein described is only'onc of the 3 many embodiments my invention .may take, and I do not Wish to be limited in the'practice of my invention nor in claims, to the particular embodiment I, forth. I

What I claim and desire to secure by Letters Patent, is:
